One of the same-sex couples who challenged Puerto Rico’s same-sex marriage ban exchanged vows on Friday.

Yolanda Arroyo Pizarro and Zulma Oliveras Vega tied the knot at a restaurant in San Juan’s Santurce neighborhood during a ceremony that took place amid tight security. El Nuevo Día, a Puerto Rican newspaper, reported that Ada Conde Vidal, president of the Human Rights Foundation of Puerto Rico, was the maid of honor.

Arroyo and Oliveras were among four same-sex couples who joined a lawsuit against the U.S. commonwealth’s gay nuptials ban that Conde and her wife, Ivonne Álvarez Vélez, filed in U.S. District Court in March 2014. Puerto Rico Para Tod@s was also a plaintiff in the case.
